HY DROCARBON-VAPOR-.BURNING LAMP.

SPECIFICATION forming part of Letters Patent No. 681,282, dated August 27, 1901. Application iiled (lune 26, 1900. Serial No. 21,610. (No model.)

To all whom t nung/concern.;

Be it known that I, ALBERT Ronenns WAR- NER, a citizen of the United States, residing at N o. 2020 Oxford street,in the city of Philadelphia, in the county of vPhiladelphia and State of Pennsylvania, have invented certain new and useful Improvements in Hydrocarbon-Vapor-Burning Lamps, of which the following is a specification.

My invention has relation to improvements in a hydrocarbon-vapor-burning lamp of the form which has become known as a suspension-lamp, employing two or more mantles adapted to become incandescent and now commonly known as Welsbach mantles, and a lamp in which hydrocarbon oil is thoroughly vaporized and afterward mixed with air prior to its consumption in the burners of the lamp; and in such connection it relates more particularly to the construction of the lamp and arrangement of the parts of the same for the said purposes.

My invention, stated in general terms, consists of a hydrocarbon-vapor-burning lamp when constructed and arranged in substantially the manner hereinafter described and claimed.

The nature and scope of my present invention will be more fully understood from the following description, taken in connection with the accompanying drawings, .forming part hereof, in which- Figure 1 is a vertical longitudinal sectional View of a lamp embodying main features of my invention. Fig. 2 is a vertical sectional view of the upper portion of the lamp on the line m oc of Fig. 3. Fig. 3 is a cross-sectional View on the line 3 3 of Fig. 1. Fig. 4; is a view, partly in section and partly in elevation, of the vaporizing-tubes; and Fig. 5 is a vertical sectional view of a portion of the burnerbody and in broken section of a portion of the mantle connected therewith.

Referring to the drawings, A represents an exterior casing or hood surrounding a portion of the working parts of the lamp. Beneath said casing is suitably secured a globe a, within which is coniined two or more incandescent-mantles b and b', suspended from the `versely of the lamp and communicating with a vaporizing-coil d4 and' tube d', into which the oil is lfed under pressure by means of a pipe d2 from a suitable source of oil-supply (not shown) and in which the oil is vaporized. This oil-supply, in its connection with the vaporizing-coil d4 and tube d', is provided with a check-valve or stop-cock d3, which controls the supply of oil entering the vaporizing` coil d4 and tube d. Above the vaporizingcoil d4 and tube d is located a jet-tube e, connected with a source of independent gas-sup ply and controlled by an electric gas-igniting device E, of any well-,known type-for instance, a magnetic device, as illustrated. This device is connected by lines 1 and 2 with a battery mand operated by push-buttons fm and m2, as illustrated in Fig. 1, one pushbutton serving to turn on the gas and to ig: nite the same, whereas the other stops the iiow of gas.- y

' The sparking device consists of two wires g and g of the electric igniter E, and they are locatedadjacent to the end of the jet-tube e, as clearly illustrated in Figs. 1 and 2, whereby when the current is made by the operation of one or the other of the push-buttons m' or m2 the gas passing through the jettubee is ignited. The jet by striking upon the tube d is divided into two small flames e2 and e3, one branch e2 being directed upon the coil d4 and the other branch c3 of the flame being deflected in the direction of and against the burner-bodies c and c for effecting the ignition of the gases issuing from the burners. The division of the Iiame issuing from the jet-tube is induced by the deliecting of the flame to the side of the vaporizing-tube d in order that one portion of said flame under pressure may be directed through the coil of the vaporiZing-tube d for heating the same to a high degree, and therebyrhastening the initial vaporization of the oil in its passage through said tube and anterior to the expansion of the vaporized oilin the chamber or tube d, as illustrated in Figs. 2 and 4. After initial vaporization the ow of gas through the j et-tube e is cutoff by means of one of the push-buttons m or m2, and thereafter the heat of the burners c and o' continues the vaporization of the oil Aiiowing through the vaporizing-coil d4, tube d', and chamber d.

IOO

The expansion of vapor in the chamber d is sufficient to induce sufficient pressure to project the vaporized oil downward through the burners c and c' with su icient force as that when ignited the flames will properly incandesce the entire body of the respective mantles b and b. The expanding-chamberd, being highly heated, serves further to vaporize all particles ot oil escaping through the coil d4 and tube d' before the vapor reaches the burner. The entrance of air into the globe for supporting combustion of issuing ignited gases at the burners in the presence of the mantles is always under less pressure than the downward pressure of the flame from the burners, thus insuring a uniform and high degree of illumination from said mantles.

1L and 'i' are vertical air-tubes extending through the exhaust chamber or receptacle D of the lam p. These tubes conduct air from the exterior of the chamber D to the burners.

From the base of the said chamber or recepl 0 a substantially air-tight receptacle, a series tacle D is suspended the globe a, suitably clamped thereto. The receptacle D and globe a together form a substantially air-tight inclosure for the working parts of the lamp, and the vertical tubes are secured at their upper ends in stuiiingboxes h2 and h3 and traverse the receptacle D and open out into the external air, as clearly illustrated in Fig, 2. The provision of stuffing-boxes at the upper ends of the tubes and t" permits said tubes t' and t" to expand or contract under variations of temperature without impair-ing the air-tight character of the inclosure for the working parts.

The vaporizing-tube d at the point of junc- Lion of the oil-supply therewith is provided with a stuttingbox j, similar to those already described,to compensate for expansion or contraction of this tube when either in or out of use.

Within each of the burner-bodies c and c' is provided a vertical tube 7o, made tapering atits lower extremity, and within which body and below said tube 7a are provided a series of super-posed truncated-coue-shaped openended hoods 7o', acting on the injector principle,to permit of more complete commingling of the air fed by the tube t' or c" to the gas entering the burner-body c or c', and thus to effeet more uniform or complete admixture of the air with the gas prior to consuming of the gas at the burners.

From the upper part of the exhaust-chainber D is provided a tube or oft-take fn., surrounded by asbestos or other heat-non-conducting material o, as illustrated in Figs. 1 and 2, whereby the heat generated by the lamp, as well as the gases of combustion, may be conveyed from the lamp-body to a point outside the apartment to which the lamp is hung without materially affecting the temperature of the apartment and at the same time the lamp with its working parts and the globe within which is confined the burners maintained air-tight.

The noises incident to the pressure under device of the electric igniter.

which the gases are delivered to the burner by this type of vapor-burning lamp are not only lessened,but also deadened. LThe smell of unvaporized and unconsumed oil and the drip of free oil from the burners is avoided by passing the oil after Vaporization in the coil d4 into the expanding-chamber d prior to its delivery to the burners and prior to its mixture with air. Moreover, the lamp is more efcient due to the manner of ignition of the gas through the divided jets bythe sparking Again, by arranging the parts of the lamp as described and illustrated the lowering of the lamp for lighting is avoided, because the starting of vaporization of the oil as well as the lighting of the burners of the lamps are under control through the said electric igniting device E.

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-
